Alum Creek Prothonotary Warbler Nest Jars - Tuttle


E-mail from, and photos by Dick Tuttle:
Hello Everyone,
On 3 May 2007, I used my canoe to install ten pairs of Prothonotary Warbler "nest jars" along a mile-long stretch of Alum Creek from the Rt. 521 bridge at Kilbourne, Ohio to Alum Creek Lake. This project is fashioned after a successful project started in 1992 along the Upper Cuyahoga River in Geauga County in northeast Ohio. Dan Best, naturalist with the Geauga County Metro Parks, and two other conservationists, the late Duane Ferris and Andrew Fondrk installed plastic Metamucil jars mounted on telescoping PVC pipe sections to accommodate nesting warblers. A 2001 report had Prothonotaries nesting in ten of 18 jars.
The stream that feeds Alum Creek Lake looks very much like the Upper Cuyahoga River, so I started collecting Metamucil jars for my own project but fell short. I was forced to manufactured my own jars by sawing four-inch PVC drain pipe into the proper lengths, added wooden floors, and topped each jar with a PVC cap held in place by a small screw. Each jar has a 1-1/4 inch entrance hole and two one-inch ventilation holes that are screened. I painted each jar with two coats of "Yucca Green" latex paint. A steel hose clamp holds each jar to a five-foot-long piece of 1-1/4 inch PVC that telescopes up and down a steel pipe that sticks up from the stream or lake bottom. A second hose clamp holds the "sleeve" and jar at the proper distance above the water, higher than summer flood levels.
I check my Prothonotary nest jars from my canoe (or kayak) just like they do in Geauga County. Since their installation, I have monitored the nest jar water trail twice, and so far, I am excited by the results. Seven of ten locations show warbler activity. One jar sports five eggs, one has a completed nest, and five locations have jars with moss added by male Prothonotaries. A Tree Swallow nest with five eggs in found in one jar and anther holds a wren's stick nest. Since I did not have time to paint the jars' interiors, I am pleased that three species of birds have accepted the jars' white nest chambers.
Three pairs of nest jars are located in the lake, all visible to viewers watching Osprey Platform No. One (most northern) from Hogback Road. Warblers have visited two of the nest jar pairs by adding moss.
Since PVC nest jars heat up when exposed to the sun, I tried to install them where they are shaded for all or most of the day. I have an idea for a simple roof that will shade the nest chambers next year. Also, I tried to place the mounts where they are safe from strong currents should there be a high water event during the nesting season.
I am experimenting and I will share the results. So far, "sweet, sweet, sweet, sweet, sweet" is a fairly common song along the target area of Alum Creek.
Warbler on, Dick Tuttle
